NAME
raw2tiff - create a TIFF file from a raw data file
SYNOPSIS
raw2tiff [ options ] *input.raw output.tif
DESCRIPTION
raw2tiff converts a raw byte sequence into TIFF. By default, the TIFF image is created
with data samples packed (PlanarConfiguration=1), compressed with the PackBits algorithm
(Compression=32773), and with each strip no more than 8 kilobytes. These characteristics
can overridden, or explicitly specified with the options described below.
OPTIONS
-H number
Size of input image file header in bytes (0 by default). This amount of data just
will be skipped from the start of file while reading.
-w number
Width of input image in pixels (can be guessed, see Guessing the image geometry
below).
option -b number
number of bands in input image (1 by default).
-d datatype
type of samples in input image, where datatype may be one of:
┌──────────┬──────────────────────────────────┐
│Data type │ Description │
├──────────┼──────────────────────────────────┤
│byte │ 8-bit unsigned integer (default) │
├──────────┼──────────────────────────────────┤

└──────────┴──────────────────────────────────┘
-i config
type of sample interleaving in input image, where config may be one of:
┌──────────────┬──────────────────────────────────┐
│Configuration │ Description │
├──────────────┼──────────────────────────────────┤
│pixel │ pixel interleaved data (default) │
├──────────────┼──────────────────────────────────┤

└──────────────┴──────────────────────────────────┘
-p photo
photometric interpretation (color space) of the input image, where photo may be one
of:
┌────────────┬──────────────────────────────────┐
│Photometric │ Description │
├────────────┼──────────────────────────────────┤
│miniswhite │ white color represented with 0 │
│ │ value │
├────────────┼──────────────────────────────────┤

│ │ value (default) │
├────────────┼──────────────────────────────────┤

│ │ model │
├────────────┼──────────────────────────────────┤
│ycbcr │ image has YCbCr color model │
├────────────┼──────────────────────────────────┤
│cielab │ image has CIE L*a*b color model │
├────────────┼──────────────────────────────────┤
│icclab │ image has ICC L*a*b color model │
├────────────┼──────────────────────────────────┤
│itulab │ image has ITU L*a*b color model │
└────────────┴──────────────────────────────────┘
-s swap bytes fetched from the input file.
-L input data has LSB2MSB bit order (default).
-M input data has MSB2LSB bit order.
-c Specify a compression scheme to use when writing image data: -c none for no
compression, -c packbits for the PackBits compression algorithm (the default), -c
jpeg for the baseline JPEG compression algorithm, -c zip for the Deflate
compression algorithm, -c lzw for Lempel-Ziv & Welch.
GUESSING THE IMAGE GEOMETRY
raw2tif can guess image width and height in case one or both of these parameters are not
specified. If you omit one of those parameters, the complementary one will be calculated
based on the file size (taking into account header size, number of bands and data type).
If you omit both parameters, the statistical approach will be used. Utility will compute
correlation coefficient between two lines at the image center using several appropriate
line sizes and the highest absolute value of the coefficient will indicate the right line
size. That is why you should be cautious with the very large images, because guessing
process may take a while (depending on your system performance). Of course, the utility
can't guess the header size, number of bands and data type, so it should be specified
manually. If you don't know anything about your image, just try with the several
combinations of those options.
There is no magic, it is just a mathematical statistics, so it can be wrong in some cases.
But for most ordinary images guessing method will work fine.
